[Amps] close to off topic - how to read antenna R + jX ??

All,
I have become interested in leaning more about what is actually going on
at the antenna. I have a vertical and would like to measure it.
First I have an Autek RF-1. It measures swr, Z, L, and C at a preset f.
I am not certain what the L and C are reading. When I measure a 50 Ohm
terminator at 7.2 MHz it actually reads a Z of 50 and an SWR of 1.0.
However the L and C readings are of 2 uH and 2500 pf. What are these
actually measuring? The values are very close to those from the antenna.
How can I actually measure the L and or C component of the antenna? If I
use an impedance bridge at the frequency will it measure L (or C)?
I hope this is close enough to topic.
Dan
